Use Nebula Console to connect to NebulaGraph

Prerequisites

  • The machine you plan to run Nebula Console on has network access to NebulaGraph services.

  • The Nebula Console version is compatible with the NebulaGraph version.

    Note

    The same version of Nebula Console and NebulaGraph is the most compatible. There may be compatibility issues when connecting to NebulaGraph with a different version of Nebula Console. You may be unable to connenct to NebulaGraph due to the compatibiltiy issue and an error message incompatible version between client and server is displayed.

  2. In the Assets area, find the correct binary file for the machine where you want to run Nebula Console and download the file to the machine.

  3. (Optional) Rename the binary file to nebula-console for convenience.

    Note

    For Windows, rename the file to nebula-console.exe.

  4. On the machine to run Nebula Console, grant the execute permission of the nebula-console binary file to the user.

    Note

    For Windows, skip this step.

    $ chmod 111 nebula-console

  5. In the command line interface, change the working directory to the one where the nebula-console binary file is stored.

  6. Run the following command to connect to NebulaGraph.

    • For Linux or macOS:
    $ ./nebula-console -addr <ip> -port <port> -u <username> -p <password>
[-t 120] [-e "nGQL_statement" | -f filename.nGQL]
    • For Windows:
    > nebula-console.exe -addr <ip> -port <port> -u <username> -p <password>
